The fragrance is a fast-growing tree tree, rich in nutrients and fragrances, which has traditionally been the favorite vegetable of our people。
There are three techniques:
I: cultivation
The fragrance usually begins to grow in 78 years, and a strong, 1015-year-old parent tree should be harvested. When the fruit matures, its hyena changes from green to brown and should be harvested in a timely manner. It's too late for the berries to crack and the seeds to be picked. After recovery, after a few days of drying up, the seeds are removed, mixed, hidden. Scorched seeds weigh 15 g dry, about 65 dents per kilogram, with a gerontization rate of 60 per cent。
Soil fertility, good drainage and low groundwater levels are selected. The fragrance is a fast-growing tree and extra organic fertilizer should be applied to the ground in order to ensure the growth of seedlings。
Seeds are to be picked locally or in neighbouring areas, and the fragrance of the south is too cold to be moved to the north. The seeding varies from region to region, usually in march to april, with multiple strippings ranging from 25 to 30 cm and an acre planting of 3. 4 kg. Pre-plant seeds can be immersed day and night with 20-30°c clean water, extracting seedlings and keeping temperatures at 20-25°c. Once the seeds have broken their mouths, they can be planted. In this way, the soil can be released eight days earlier and it will be fully grown. Saplings are 5 cm-timed, set at 10 cm-high, 15-20 cm, producing about 15,000 seedlings per acre。
A slow-growing stage of seedlings, combined with pine soil, and the pursuit of a small amount of nitrogen fertilizer seedlings, generally began in early june with a long-term shift to a boom, requiring high levels of fertility, mainly nitrogen fertilizer, and appropriate application of some phosphate potassium fertilizer. A significant decline in growth rates after september should be followed by the application of potassium phosphorus fertilization to promote woodification. They can leave when they are 100 cm tall。
Two: root breeding
This method is simple, alive and of good quality. The root is collected on the basis of one to two years of tree production, and the side roots on the robust parent tree are available. Roots are collected in the spring between march and april and cut in time, 10 to 20 cm long, with small cuttings tilted, as appropriate. Each acre has 2500-3000 seedlings. In order to prevent root healing tissues from decaying and to ensure temperature, water is generally not watered. When 10 centimetres are tall, go to the weak and sprout one。
Iii: plug-in
During the rainy season of may-july, branches selected for semi-timberation in the current year, 10-15 cm length each, were typically kept in 3 sides, with an upper cut-off range of 0. 8 cm or so, with a lower cut-off of 45 cm or so below the lower sprouts and a lower cut-off of 2 seconds in a 500 ppm sodium acetic acid solution, which was then inserted in the ablaze decomposition soil at a depth of 8 cm, then covered with plastic sheeting, often sprayed water to protect the temperature, and could then be rooted for 50 days or so.
